Choosing a design-build approach for your next project can streamline and simplify your approach to construction. It’s a way for owners to work with one team from start to finish, with greater collaboration between the design and construction functions from the project start. Instead of managing multiple sub-consultants you will work with one design-build team typically led by the general contractor.

TWM is a member of the Design-Build Institute of America.


At TWM, it’s been our experience that when the planning, surveying, architectural design, and engineering phases are performed accurately and with care, then the rest of the construction phases run more smoothly. Our goal is to design every project as if we are performing Value Engineering services, so your project is completed without wasting any precious resources on unnecessary design elements. When done well, engineering blends form and function.

Our engineers will work with you throughout the entire process. Once we have completed the final engineering designs, we can provide construction phase services to help move your project from concept to reality.


Design-Build is a streamlined method that saves time for clients by working directly with a single point of contact to quickly resolve issues and find solutions.


Cost Control

Budget needs and construction costs can be shared and accurately priced before making any design plans to accommodate more affordable design options.

As a full-service engineering consultant, we provide a broad range of design projects and related services. Besides Design-Build, we also focus on many other civil and structural services as well as geospatial services. With our depth of capabilities, we can deliver cost-effective solutions to meet any need or challenge.

Our transportation group provides safe, convenient, and economical solutions for roads, trails, and traffic management.

Our large structural group delivers innovative bridge designs and associated structures that are cost-effective, safe, easily constructible, and durable.

Our land development group provides complete civil engineering services, starting with conceptual plans and ending with project approval and construction.

Our water infrastructure group is devoted to the protection of our waters, environmental responsibilities, and designing innovative wastewater facilities.

We use specialized tools that accurately evaluate and rank pavement to forecast both short- and long-term budgets for our government clients.

Our construction engineering staff ensure that engineering design skills are effectively translated into the actual construction of the project.

We provide robotic video inspections, flow monitoring, sewer testing for new construction, and push camera inspections for any size project.


That’s our company mission and our promise to you. Our success is built upon a solid reputation for getting the job done right. One thing we are particularly proud of is approximately 95% of TWM’s work comes from repeat business.
